Lately, the optical research community has shown considerable interest in wave propagation phenomena in discrete structures.
Arrays or lattices of evanescently
coupled waveguides or chains of coupled microresonators are prime examples of structures where discrete optical wave dynamics can be observed. One question
that has naturally arisen is whether the Talbot effect is also possible in discrete systems. more>>

A new type of tunable optical fiber is based on photonic crystal fibers (PCFs), which have a cross-section that usually consists of an air/silica microstructure that is invariant along the fiber axis. more>>

In a recent experiment, we demonstrated the transfer of a qubit from a photon at the telecom wavelength of 1312 nm to another photon around 712 nm, a wavelength close to that of alkaline atomic transitions. more>>
